Dot laser technology compared to traditional screen printing process is concerned, one of the advantages of laser machine outlets are: more suitable for small batch processing and proofing manufacturing and other occasions. For network printing process, proofing costs and very high costs, production line configuration 100-1000 stage small batch processing is almost impossible. For laser machine outlets, even though a large monolithic samples and customization also very convenient, only need to change the network layout program and processing parameters on the computer can be realized at the same time, because the process involves printing the ink couplers, batch differences, silk screen product consistency is poor, and thus the yield is low, usually not higher than 75%, while the laser machine network without the use of printed media, relying solely on a certain energy of the laser spot on the PMMA burning generating pits, so consistency is significantly improved, generally greater than 95%. Because of this salient reason, laser and dot proofing design more suitable for use in the generation of manufacturing and new product development. RBI machine laser light guide (also known as: laser light guide plate outlets machine, LED light guide plate outlets machine) are used extensively for lighting, lighting, advertising, energy, TV and other fields. Light guide plates network making, molding, without printing, cutting, edging and other processes. The finished product is higher than the brightness of screen printed products, and smooth edges, can form a specular reflection, outlets retraction, increases the refractive index. The light guide plate engraving machine is widely used (thin light box, crystal light guide plate engraving drawn line.) Ultra-thin light box, crystal light guide plate engraving drawn line.
